Review: Easy - The product seems to be really easy to use. Im not sure its entirely accurate it seemed to give a few false results in shallow water 2ftish where i could see the bottom but other than that no issues at all. I think i should mention if like me you are casting out with it use a heavy line. I used 12lb casting to about 60yrds and managed to snap line.

Hola a todos, iré ampliando información sobre el producto según se hagan pruebas. El envío a sido super rápido, muy bien embalado , sin ningún daño en el embalaje , la presentación del empaquetado es súper profesional, en la caja se incluye la propia sonda, las pantalla receptora y cables para su carga, tanto a enchufe como cargador del coche, también se incluye los enganches para poder lanzar con caña de pesca o a barco cebador. Es súper intuitiva al usarse y tiene opciones de varios idiomas, entre ellos español al igual que en las instrucciones, que las podemos encontrar en español.
